Successfully got the science and technology town.

The people of the extraordinary network company also simply cleaned up and moved into the new office area smoothly under the command of Henry Targaryen.

Song Fan's villa was quiet again for the time being.

Briefly cleaned up the remnants of the crowd and cleaned up the room.

Suddenly, I received a call from Qin Kexin, saying that a professor from Qingbei would come to visit later.

"Song Fan, do you remember the note you used to prove Goldbach's conjecture last time?" Qin Kexin briefly explained the reason for the incident.

After Qin Kexin showed the notebook to the retired old professor Yu Lao, Yu Lao stabbed the matter to Qingbei University again, and quickly attracted attention.

So today, Qingbei sent people to visit the mathematical wizards in Jiangnan.

"I'm sorry, Song Fan. Without your consent, I casually showed the note......" Qin Kexin was apologetic.

"It's fine. Come on. Song Fan agreed. If you can give back to the society and the university, it will be a good thing.

Just when Qin Kexin was talking to Song Fan.

A flight from Yanjing to Jiangnan has landed.

"Lao Yu, I hope that the young man you introduced will not disappoint me!" A thin old man, dressed in a simple Mao suit, although he is very old, his body is straight and his waist is straight. Walk with a sonorous force.

"Don't worry, Lao Cui! I saw that notebook with my own eyes, it shocked me so much! If I hadn't waited for you to come, I would have gone to meet that mathematical genius a long time ago!" Yu Lao laughed happily.

Yu Lao is the tutor hired by Qin Kexin's family and the old professor of the Department of Mathematics who retired from Qingbei University.

And the other old man in the tunic is a former colleague of Yu Lao, who is also the deputy director of the Department of Mathematics of Qingbei University. His name is Cui Gongming.

In the eyes of others, these two old men are ordinary. But in the academic world, the names of the two are like Mount Tai, which is admired by many scholars.

Cui Gongming, in particular, is a few years younger than Yu Chengsui, and his academic ability is even more top-notch! At the same time, he is also an academician of the Chinese Academy of Sciences and deputy director of the Institute of Mathematics. The biggest names in the world of mathematics!

boarded the business car sent by the Qin family to pick up the airport, and the two old men embarked on the road to inspect Song Fan.

"Wait. Let's go to the boy's school first......" Halfway through, Cui Gongming suddenly proposed.

"Why don't you go to his house to meet him directly?" Yu Chengsui was a little puzzled. "The young man seemed to be at home from school. ”

"It's about to take the college entrance examination, but he has suspended his studies? What a proud talent!" Cui Gongming has seen too many talented genius students, but in the end, they all went to mediocrity.

Talent, though important. But diligence is just as key!

"Let's go to his school first. I still don't quite believe that a high school student can prove Goldbach's conjecture. Cui Gongming proposed, "Let's go and see what he usually does, and what unique ideas he has for solving problems." This can't be faked!"

Yu Chengsui felt that it made sense.

A lot of times, the final grade doesn't necessarily mean anything. It may be more convincing to look at a person's usual achievements.

If this young man really has the ability to prove Goldbach's conjecture. Then from his daily homework and answers, you can find something different.

"Okay! Let's go to Jiangnan No. 1 Middle School first!"

Soon, the two old professors arrived at the century-old school, the most famous high school in Jiangnan.

When the professor of Qingbei University visited, President Hao personally welcomed him to the office, sat down for tea, and waited carefully.

At the same time, I am curious, what are these two old professors coming here to investigate?

Could it be that the top students here were inspected in advance?

But generally this kind of thing is the responsibility of the school's admissions office, and I haven't seen any student inspected, and the professor has personally come out.

Principal Hao was about to recommend himself and recommend several top students in the school.

As a result, the two of them, named and named, asked Song Fan of the third class, homework on weekdays, and exam papers.

"Song Fan?" Hearing his father's name, Principal Hao was surprised and delighted!

'Is my dad so awesome?' has alarmed the professors in Qingbei to come and see him?'

Principal Hao hurriedly informed the teachers of the third class and brought Song Fan's usual exam papers and homework to the office.

Soon, the exam papers and workbooks were moved.

Principal Hao was the first to take over the test papers, and when he looked at them, he secretly screamed that it was not good.

'My dad's score...... It's a bit hard to handle......

Principal Hao was a little remorseful. If you know about it, let the teachers know it and pick and choose. If the results are too bad, don't get them.

'These two professors, seeing my dad's grades, are they a little embarrassed?'

Sure enough.

Cui Gongming picked up Song Fan's first test paper and almost didn't memorize it.

"Thirty points?" Cui Gongming looked at the math test paper, except for the multiple choice questions in the ABCD class in the front, he got a few correct. The rest of the questions are all blank.

Even Yu Cheng, who had great expectations for Song Fan, couldn't help but shake his head and sigh after looking at Song Fan's homework on weekdays.

"This is ...... achievement"

It's a little worse!

Not only mathematics, but other subjects, in addition to Chinese -

The two of them briefly looked at it, and Song Fan's results in the past three years have hardly passed a few times!

Not to mention the homework on weekdays.

"It's really bullshit!" Cui Gongming threw his homework book on the ground, his face turned blue with anger.

I have never taught a student with such bad grades in my life!

Say that this kind of student can prove the Goldbach conjecture?

I'm afraid that even Goldbach will have to come back to life.

"Lao Yu, what do you think?" Cui Gongming pouted, already dead.

"Perhaps...... He's biased, right?" Yu Chengsui smiled bitterly. I can't find a good reason to explain all this.

"Partial to the subject?" Cui Gongming laughed angrily, "Is he biased in all subjects?

At this time, Principal Hao also looked at Song Fan's usual exam papers, and his head was almost big.

He was still remorseful just now, and he didn't send it selectively.

Now Principal Hao finds that he is thinking too much.

Because there is no one that can be mastered at all. There's no need to pick and choose.

"There is!" Principal Hao suddenly found Song Fan, the most recent one, the math test paper with 130 points. "Let's take a look at this exam paper. 130 points, and there are few people in the whole school who can get this score. ”

Principal Hao wiped his sweat, it was like looking for a needle in a haystack. Finally picked out a copy that I could read.

But Cui Gongming and Yu Chengsui are too lazy to watch anymore.

Soon, the two got up to say goodbye and left disappointed.

Seeing the backs of the two Qingbei professors leaving, President Hao muttered in his heart: "Dad! I may have messed up your university entrance qualification without examination." Don't blame me, I really can't help my son. ”

"Lao Yu, what a waste of my time...... That is, you, if you change someone else, and play me like this, I would have scolded him to death a long time ago!"

Cui Gongming can't wait to fly back to Yanjing now.

"Hehe, I'm here, just accompany me around Jiangnan. "Yu Chengsui's mentality is good.

"Can you still laugh?" Cui Gong glanced at his old friend in understanding, "You are retired, and I haven't retired yet!"

"Let's go......" Yu Chengsui opened the car door.

"Where?"

"Go to the boy's house and sit down. It's all here, so we have to see each other. By the way, where did he get the proof of Goldbach's conjecture......"
